Pendulum Waves
You may recall from a Mechanics course that the period of a pendulum is proportional to the square root of the length of the line suspending the weight - i.e., the longer the pendulum, the slower it swings.
Cambridge students built a device with a series of 15 pendulums in a row, each one slightly longer than its neighbor, then set them in motion and filmed the result.
The resulting patterns in this short video are quite fascinating to watch.

Dude, I’m complaining to the boss about you if I don’t get amy more work done because I’m watching that over and over again. Especially since it links to other cool ones like this one: http://www.youtube.com/watch?v=U9PZizBDBZw&feature=relmfu
Excellent!
